ROAD-RESURFACING- APPARATUS.

Application filed December 6, 1922. Serial No. 238,145.

This invention relates to road re-surfacing apparatus, and has more particular referencer to simple and efficient means for facilitating re-surfacing of water-bound bitu# minous and concrete roads to predeterminedv gradesk by the use of road rfi-surfacing drags of the type shown in my co-pending applica`r tio-n upon road resurfacing apparatus, Serial No. 220,984, iiled September 2l, 1927.

More particularly, the present invention aims to provide simple and eilicient means which may be readily placed into practical use with the' expenditure of a minimum amount of vtime and labor as well as at a relatively low cost,to furnish a track or way over which the runners oi' a road surfacing drag` maybe readily drawn and by means of which the drag may be caused to travel in the proper position and at the required eflevation to insure resurfacing of the road ata predetermined grade. y .n Other objects will appear as the nature of the inventionisl better understood, and the same consists in the novel form, combination and arrangement of parts herinafter more fullydescribed, shown in the accompanying drawings and claimed; y In the, drawings, wherein like reference characters indicate corresponding parts throughout the several views, v v

Referring more in detail to the drawings, r

In using a road resurfacing drag of the type specified above,\a plurality of steel pins or stakes l2 are driven into ,the ground along the edge of the roadway being surfaced so as to effectively guide vthe drag in a straight o r proper path'of travel When drawn ahead, the stake 12l being provided at suitable intervals to insure engagement of the outer side oi' the outermost runner 5 with a plurality ofthe stakes at all times.

Y In accordance with the present invention it is contemplated' that the grade will be rock or lai-deut in vany preferred or well known'rjnanner with the elevation at the outeredgei (if the roadway marked on tlie, stakes 12.

Il prQvide number o f relatively large disks 13, in number of sets of different thicknesses, the disks of each set being oit uniform thickness throughout and having central'openings 13a to permit the same to be readily placedover and onto thel stakes 12. The disks 173 are off such diameter as to provide ample' tracking surface' at the vinner sides oi'thestakes 12 for riding of the adjacent Outer runner 5. of the drag thereover, and by vproviding one or more disks of sclected thickness upon each of the stakes 12, the exposed ul per` disk surface at each stake may be provi( ed level o'r vflush with the grade mark on said stakes. As the normal elevation of the road surface being repaired will vary at differentpoints, the disks employed in connection with each stake will be selected to, effect the desired result as illustrated in Figure 3 wherein a single'tl'ii'ck and a single thin diskl are employed in conjunction with the yfirst stake from the left of Figure 3, a

single -thick disk is employed with the intermediate stake of said figure, and a thick disk together with two thin disks are employed in conjunction with the right hand stake of said Figure 3. The exposed upper disk surfaces related to all of the stakes will thus be provided in a-common plane so that the outer side of the drag will be properly supported at the proper elevation in being drawn ahead over the disk. It will be noted that the disks are free to turn on the stake 12 and in this way facilitate the forward travel of the drag.

In addition to the stake 12 and disk 13 for guiding and supporting the outer side of the drag, l provide a plurality of relatively smaller disks 1/1 that are adapted to be placed and secured upon the surface of the roadway in position to have the inner runner' 5 of the drag travel thereover. These disks-14 will also be provided in sets of different thicknesses so that they may be provided in proper thickness and number at different points along thecenter of the road to present upper surfaces flush with the predetermined grade whereby the inner side of the drag will be properly supported at the correct elevation during the forward travel of the drag in the re-surfacing operation.

The disks 14; will be provided at suitable intervals so as to insurev engagement of the inner runner 5 of the drag with a plurality thereof at all times, and in order to facilitate fastening of the disks 14 in their proper places upon the road, said disks are provided with central openings 15 lwhich are enlarged or counter-sunk as at 16 at the upper sides of the disks to receive the heads 17 of spikes 18 which are driven through the openings 15 into the ground. In this way the heads 17 of the spikes 18 may be positioned to not project above the upper surface of the disks 14 and interfere with the riding of the inner runner 5 of the drag over the upper surface of said disks 14 at the proper elevation. The disks 14 are also preferably rotatable on the spikes 18 so as to facilitate the travel of the inner runner 5 of the drag thereover in case a greater amount of friction may be eX- pcrienced between the runners and the disks at either side of the axes of the spikes 18. As shown in Figure 2, disks 14 will necessarily be provided of different thicknesses at diHerent points, and in some cases a plurality of the disks 14 will have to be superimposed to present an upper disks surface' at the required elevation.

vA trackway provided in accordance with the above may be readily laid with the eX- penditure of a minimum amount of time and labor and at a comparatively small cost. Moreover, a minimum amount of friction between the track forming members and the runners of the drag will be had so as to facilitate travel of the drag with the eX- pendit-ure of a minimum amount of power.

With the grades properly run or determined, the disks may be properly laid by unskilled labor and the selection of disks of proper thickness or combined thicknesses will not consume an objectionable amount of time.

It will thus be seen that simple means is provided for insuring the production of a smooth and uniform surface for the road at given grades when the road re-surfacing apparatus is drawn over the disks or the trackway formed thereby.
